Salt and vinegar chips are so much more addictive than plain or barbecue-flavoured ones. We wanted to recreate this delightful sensation of dipping into a bag of chips with a potato recipe that uses the same flavour profiles. So serve crushed, crispy potatoes, generously sprinkled with dill, along with mayo stretched with white vinegar, salt and sugar. Be ready for an explosion of flavour to accompany your Sunday roast chicken.
